This invention relates to a crystalline molecular sieve having, in its as-synthesized form, an X-ray diffraction pattern including d-spacing maxima at 13.18&#xb1;0.25 and 12.33&#xb1;0.23 Angstroms, wherein the peak intensity of the d-spacing maximum at 13.18&#xb1;0.25 Angstroms is at least as great as 90% of the peak intensity of the d-spacing maximum at 12.33&#xb1;0.23 Angstroms. This invention also relates to a method of making thereof.

Molecular sieve composition (EMM-10-P), its method of making, and use for hydrocarbon conversions

This invention relates to a process for hydrocarbon conversion comprising contacting a hydrocarbon feedstock with a crystalline molecular sieve, in its ammonium exchanged form or in its calcined form, under conversion conditions to form a conversion product, said crystalline molecular sieve comprising unit cells with MWW topology and is characterized by diffraction streaking from the unit cell arrangement in the c direction as evidenced by the arced hk0 patterns of electron diffraction pattern.

Molecular sieve composition (EMM-10), its method of making, and use for hydrocarbon conversions

This disclosure relates to a process for hydrocarbon conversion comprising contacting, under conversion conditions, a feedstock suitable for hydrocarbon conversion with a catalyst comprising an EMM-10 family molecular sieve.

Hydrocarbon conversion process using EMM-10 family molecular sieve

A porous material comprises oxides of silicon and aluminum and is substantially free of X-ray diffraction peaks in its calcined form. The material is characterized by the following properties:

Amorphous acidic materials, their synthesis and use

This invention relates to a crystalline molecular sieve, in its ammonium exchanged form or in its calcined form, comprising unit cells with MWW topology, said crystalline molecular sieve is characterized by diffraction streaking from the unit cell arrangement in the c direction. The crystalline molecular sieve is further characterized by the arced hk0 patterns of electron diffraction pattern. The crystalline molecular sieve is further characterized by the unit cells streaking along c direction. This invention also relates to a method of making thereof.

The distillate catalytic hydrodesulfurization of hydrocarbon fuels wherein the optimum hydrogen treat gas rate to maximize desulfurization is determined and introduced into the reaction zone to maintain a controlled amount of hydrogen at the surface of the catalyst during hydrodesulfurization.

Deep hydrodesulfurization of hydrocarbon feedstreams

A process for oligomerizing isobutene includes contacting a feedstock including isobutene with a catalyst comprising an EMM-10 molecular sieve under conditions effective to oligomerize said isobutene and produce an effluent containing less isobutene than the feedstock.

Selective oligomerization of isobutene

This invention relates to a process for selectively hydrodesulfurizing naphtha feedstreams using a catalyst comprising at least one hydrodesulfurizing metal supported on a low acidity, ordered mesoporous support material.

Selective hydrodesulfurization process

The present invention relates to a process for preparing severely sterically hindered secondary amine ether alcohols and diamine polyalkenyl ethers by reacting a primary amino compound with a polyalkenylether glycol in the presence of a high activity nickel powder hydrogenation catalyst which is marked by high conversion of reactants and increased selectivity to desired final product.

Synthesis of severely sterically hindered amino-ether alcohols and diaminopolyalkenyl ethers using a high activity powder catalyst

This invention relates to a catalyst and process for selectively hydrodesulfurizing naphtha feedstreams using a catalyst comprising at least one hydrodesulfurizing metal supported on a low acidity, ordered mesoporous support material.

Selective hydrodesulfurization catalyst

A two stage hydrodesulfurizing process for producing low sulfur distillates. A distillate boiling range feedstock containing in excess of about 3,000 wppm sulfur is hydrodesulfurized in a first hydrodesulfurizing stage containing one or more reaction zones in the presence of hydrogen and a hydrodesulfurizing catalyst. The liquid product stream thereof is passed to a first separation stage wherein a vapor phase product stream and a liquid product stream are produced. The liquid product stream, which has a substantially lower sulfur and nitrogen content then the original feedstream is passed to a second hydrodesulfurizing stage also containing one or more reaction zones where it is reacted in the presence of hydrogen and a second hydrodesulfurizing catalyst at hydrodesulfurizing conditions. The catalyst in any one or more reaction zones is a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals.
